Tejashwi Yadav was formally appointed as RJD's National Working President on Sunday, months after RJD suffered a defeat in the Bihar Assembly election. His father and RJD supremo Lalu Yadav handed him the appointment letter. RJD won just 25 seats in Assembly election, following which Tejashwi's sister Rohini had a fallout with him. She blamed Tejashwi's aides for the loss.
